 OFFSET 0,2 COMMENTS The sequence ends with the smallest pandigital primorial, which is 61# = 117288381359406970983270 (18th primorial). If you change the criterion from "at least n distinct" to "all" the sequence becomes 1, 210, 2310, 200560490130, 1922760350154212639070, 117288381359406970983270. LINKS EXAMPLE a(1) = 210 = 7#, which shares the "1" with a(0). a(2) = 2310 = 11#, which shares more than the needed two digits with 210, namely "0", "1", and "2". a(3) = 223092870 = 23#.
